But did you really need DxO to tell you this? I doubt it. The thing that I find surprising is how many people seem to be surprised to figure out that if you want to get the most out of a good imaging system, you have to use a good lens.

Yeah, sometimes common sense is just not that common.

What I found interesting was the observation that with a 'common set of lenses' the differences weren't that large. I would have a larger difference.
